War of the Elves and Sauron

Sauron, enraged that his deception with the One Ring had been unmasked, gathered a host in Mordor and struck west into Eriador. His forces drove hard for Eregion, the realm of the Elven-smiths who had wrought the Rings of Power, catching the Noldor before adequate help could reach them. Gil-galad, ruling in Lindon, sent Elrond north with what strength he could spare, but the relief column was still on the road when Sauron's army closed around Eregion, and Celebrimbor was left to hold the city with his own people alone.

Eregion fell after a hard siege. Celebrimbor was taken and, under torment, made to disclose where the Rings of Power he had forged were kept, so that Sauron recovered the Seven and the Nine, though the bearers of the Three had already carried theirs beyond his grasp. Celebrimbor was put to death, and Sauron pressed on toward Moria, where the Dwarves barred their gates against him and refused him entry. Elrond, arriving too late to save the city, gathered its scattered survivors and led them north-east into the wild, where he founded the refuge that became Imladris. With Eregion gone, Sauron turned his full strength on the rest of Eriador and overran it, driving at last toward Lindon itself, where Gil-galad and Círdan held him off.

The Elves' position in Eriador had grown desperate by SA 1700, when a fleet sent by Tar-Minastir of Númenor reached Lindon in answer to Gil-galad's plea for aid. The Númenórean forces landed beside the besieged Elves, and together they broke Sauron's grip on the land, driving his armies back in a series of defeats. By SA 1701 Sauron had been pushed entirely out of Eriador and forced to withdraw to Mordor, bringing the war to an end and leaving the western lands free of his direct rule for a long age afterward.

The war is dated by the Tale of Years from SA 1693, the point at which the deception of the One Ring had become plain and the bearers of the Three moved to place them beyond Sauron's reach. That act marked the shift from a covert contest of craft into open hostility. For roughly two years afterward the conflict remained a matter of preparation and watchfulness rather than battle, as Sauron mustered his strength before committing it to the field.

Open war began in earnest in SA 1695, when Sauron's host crossed into Eriador with Eregion as its objective. The advance and the ensuing struggle for the Elven-smiths' realm occupied roughly two years; only in SA 1697 did the city finally fall, with Celebrimbor's death, the shutting of Moria's gates, and Elrond's founding of Imladris all falling within that same year, as the Tale of Years records them together.

The fall of Eregion did not end the campaign but opened its next stage. Rather than pressing forward at once, Sauron spent a further two years consolidating what he had won, and it was not until SA 1699 that the record marks all of Eriador as overrun by his forces. This interval between the ruin of Eregion and the subjugation of the wider region shows the war as a sustained occupation rather than a single decisive stroke.

Sauron's mastery of Eriador held for roughly a year before it was broken. The turn came in SA 1700, when Tar-Minastir, King of Númenor, answered Gil-galad's call for aid and dispatched a great fleet to Lindon. Its arrival gave the hard-pressed Elves the strength they had lacked since Eregion's fall, and the combined force began to roll back Sauron's occupation of the land he had held for two years.

The recovery of Eriador was completed within a year of the fleet's landing. By SA 1701 Sauron had been driven from the region entirely, bringing the war to a close after eight years reckoned from its formal beginning in SA 1693. The Tale of Years marks this expulsion as the war's final act, closing a conflict whose stages had run from covert unmasking, through the loss of Eregion, to a prolonged occupation, and finally to defeat at Númenórean hands.

The conflict set Sauron, commanding a host raised in Mordor, against the Elven realms of Eriador and, once battle turned against them, the Númenóreans who came to their aid. On the Elvish side, authority was divided rather than unified: Celebrimbor led Eregion and its Gwaith-i-Mírdain in the fighting that fell to them alone, while Gil-galad, as High King in Lindon, held overall leadership of the Elves of the west and directed what aid could be sent. Elrond served under Gil-galad's authority as commander of the relief force dispatched toward Eregion, a role that afterward carried over into his founding and leadership of Imladris. Círdan, ruling in the Grey Havens, stood with Gil-galad in the defense of Lindon once Sauron's advance reached that far.

The Dwarves of Khazad-dûm took no active part in the fighting but were drawn into the war's geography: when Sauron's forces reached Moria's gates, the Dwarves refused him passage and shut themselves in, denying him a route rather than joining the field against him. Sauron's own following in this war is named in the record only as a host out of Mordor, without the named subordinate commanders that later conflicts assign him.

The balance of sides shifted decisively with the entry of Númenor. Tar-Minastir, King of Númenor, committed a fleet to Gil-galad's cause upon his appeal, placing Númenórean strength alongside the Elves rather than as a neutral or later-arriving party; the two forces fought jointly to expel Sauron from Eriador. No figure is recorded as changing allegiance during the war; the sides that opened it, Sauron against the Elven realms, were the same sides that closed it, with Númenor added to the Elvish cause rather than replacing any party within it.

Eregion itself was never resettled. Where the Gwaith-i-Mírdain had once worked, the land passed into the empty country later travellers would know as Hollin, a name that preserved only the memory of what had stood there rather than any continuing Elvish presence. With that realm gone, the map of Eriador for the rest of the Second Age showed no Elvish center of consequence between Lindon in the west, still held by Gil-galad and Círdan, and the refuge Elrond had founded in the east. That refuge went on to serve, for the remainder of the age, as the principal gathering place for the region's scattered Noldor, a role it retained long after the fighting that had brought it about had ended.

The Three Rings, once carried beyond Sauron's reach, stayed concealed and unused for the rest of the Second Age: their keepers durst not wear them openly so long as Sauron held the One and could sense their working. The Seven and the Nine he had wrested from Celebrimbor did not remain idle in his hands. In the years that followed he gave them out to lords among the Dwarves and to great Men, a gift whose corrupting effect worked slowly and whose full cost, the binding of Men into the Nazgûl, became apparent only much later. The war also marked Sauron's first direct clash with Númenórean power, and the defeat he suffered at Tar-Minastir's hands left him with an enduring hatred of Númenor that would shape his dealings with that people for centuries afterward.

For Eriador itself, the immediate result was a long quiet. The Tale of Years records no event of comparable weight for a considerable stretch after Sauron's expulsion, and Lindon under Gil-galad remained the chief Elvish power in the west throughout that interval, with no rival realm arising to challenge it. This peace held until Sauron's shadow began to lengthen again many generations later, but for the Elves and Men of Eriador in the meantime, the war's end brought a respite rather than any lasting settlement of borders or power beyond the diminished shape the region had already taken.

Within The Lord of the Rings, this war is never rendered as a scene; it survives only as a chain of clipped annal-entries in the Tale of Years, the driest register the appendices employ. No character narrates it, no dialogue attends it, and the reader meets it as bare chronicle rather than story, a treatment that sets it apart from the fuller episodes the appendices otherwise allow. Unfinished Tales fills part of that silence, recounting the same years through Galadriel and Celeborn's history with more attention to motive and consequence, but even there the war remains reconstructed after the fact rather than witnessed as it unfolds, pieced together from what later ages remembered rather than shown directly.

Told this way, the war functions less as an episode to be followed than as buried weight beneath the present-day narrative. When the Fellowship reaches Moria and finds its gates barred, the closure is presented as an old fact rather than explained on the spot; a reader who has taken in the appendices already knows it dates to Sauron's assault on Eregion, so the doors carry a history the travellers themselves do not pause to recount. Rivendell's existence works the same way: the Council of Elrond gathers in a refuge whose founding, as a response to this very war, is assumed rather than narrated, so the war supplies the unspoken reason a sanctuary for the Elves exists at all in that part of Middle-earth.

The war also does quieter work in shaping how the Three Rings are understood once they resurface in the main story. Their concealment during this conflict, kept apart from Sauron's grasp before he ever wore the One openly, is the origin of the wariness with which Elrond and Galadriel later handle their own rings, careful never to name or display them even among allies. Read against that history, the caution the Elves show in the present-day narrative is not simply prudence but a habit formed in this specific war, one more case where the appendices' compressed record quietly explains behavior the main text leaves unexplained.
